(Reuters) - The Trump administration is mulling a crackdown on Chinese investments in technologies that the U.S. considers sensitive by employing a law reserved for national emergencies, among other options, Bloomberg reported, citing people familiar with the matter.

The International Emergency Economic Powers Act, enacted in 1977, allows the president to declare a national emergency in response to an "unusual and extraordinary threat."

After declaring such an emergency, the president can block transactions and seize assets.
